Identification of MHC class IIbeta resistance/susceptibility alleles to Aeromonas salmonicida in brook charr (Salvelinus fontinalis).
Pathogen-driven selection is believed to be important in the evolution and maintenance of the polymorphism of the major histocompatibility complex (MHC) genes but have been tested for very few vertebrates. In this study, we first investigate by SSCP (single strand conformational polymorphism) the diversity found at the MHC class IIbeta gene in a population of brook charr (Salvelinus fontinalis)...
متن کاملReview Cryptobia (Trypanoplasma) salmositica and salmonid cryptobiosis
Salmonid cryptobiosis is caused by Cryptobia (Trypanoplasma) salmositica. The haemoflagellate has been reported from all species of Pacific Oncorhynchus spp. on the west coast of North America. It is normally transmitted by the freshwater leech, Piscicola salmositica, in streams and rivers, and sculpins, Cottus spp., are considered important reservoir hosts. The pathogen can also survive on the...
متن کاملImmunological and Therapeutic Strategies against Salmonid Cryptobiosis
Salmonid cryptobiosis is caused by the haemoflagellate, Cryptobia salmositica. Clinical signs of the disease in salmon (Oncorhynchus spp.) include exophthalmia, general oedema, abdominal distension with ascites, anaemia, and anorexia. The disease-causing factor is a metalloprotease and the monoclonal antibody (mAb-001) against it is therapeutic. MAb-001 does not fix complement but agglutinates ...
متن کاملCryptobia iubilans infection in juvenile discus.
Four commercial producers of discus (Symphysodon aequifasciatus) were found to have fish infested with the flagellate Cryptobia iubilans. Affected fish had granulomatous gastritis, and many also had granulomatous disease of other organs. The parasite had to be differentiated from the related flagellates Spironucleus spp, which induce different lesions. Transmission electron microscopy was found...
متن کاملPankinetoplast DNA structure in a primitive bodonid flagellate, Cryptobia helicis.
The mitochondrial DNA (mtDNA) of a primitive kinetoplastid flagellate Cryptobia helicis is composed of 4.2 kb minicircles and 43 kb maxicircles. 85% and 6% of the minicircles are in the form of supercoiled (SC) and relaxed (OC) monomers, respectively. The remaining minicircles (9%) constitute catenated oligomers composed of both the SC and OC molecules. Minicircles contain bent helix and sequen...
